Answer:

look at the time for example, B's time is constant because it isn't skipping numbers like 1, 5, 3,etc.

the height is also constant because it is dividing each number by 2, 60÷2=30, 30÷2=15, 15÷2=7.5. You will notice A is not constant so (no) but B is so (yes)

Se quiere cubrir una pared con vidrios de forma triangular. La pared mide 36 m de largo y 9V3 m de alto.
Eddi Din [679]

Based on the dimensions of the wall and the triangular glass, the number of mirrors needed is 215 mirrors.

<h3>What number of mirrors are needed?</h3>

First find the area of the wall:

= 36 x 93

= 3,348 m²

The area of the triangle, assuming it is an equilateral triangle is:

= (√3/4) x 6²

= 15.59 m²

The number of mirrors needed is:

= 3,348 / 15.59

= 215 mirrors
